Richard Tutt Norris, Jr. has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Propylene polymer fibers and yarns
    Patent number: 6716511
    Abstract: Bulked continuous filament yarns comprise a plurality of substantially continuous filaments comprising propylene polymer and having recovery from compression, as measured by Plug Crush Recovery, of at least about 85%. The yarns exhibit improved resilience and are well suited as face yarns for residential, commercial and automotive carpets.
    Type: Grant
    Filed: September 12, 1997
    Date of Patent: April 6, 2004
    Assignee: BP Corporation North America Inc.
    Inventors: Bruce Howard Bersted, Richard Tutt Norris, Jr., Leonid Slutsker, Ty Jackson Stokes

  • Propylene polymer fibers and yarns
    Patent number: 6129879
    Abstract: Process for treating a textile product comprising propylene polymer fibers comprises heating the textile product with the fibers in a substantially relaxed state at at least one temperature that is below the melting point of the propylene polymer but no more than about 20.degree. C. below such melting point. In one embodiment, the propylene polymer fibers subjected to such heating are characterized by a particular crystalline microstructure as determined by small angle X-ray diffraction. In another embodiment, the propylene polymer fibers subjected to such heating are melt spun, oriented fibers heated at at least one lower temperature.
